Jan Jongkind

During the Olympic regatta of 1964 a controversy emerged between the team members (Van Duyl & Jongkind) of the Dutch Dragon. This escalated and Jongkind left Japan after the second race. After the Games the Royal Dutch Yacht Racing Union ruled that because of their behavior, both team members were not allowed to sail in International regattas for the next two years.
